Internodes with 6–7 internal septa (occasionally absent), one hydrotheca, and three one-chambered nematothecae. Hydrothecae large, deep, shorter than corresponding cormidia, with almost parallel walls in side view, but widening distally in frontal view; long axis parallel to that of internode, with depth/width at rim= 2.07–2.28 (n= 25). Perisarc thin, with a longitudinal mesial thickening on abcauline side. Intrathecal septum arising from behind hydrotheca, projecting forwards into its lumen, very reduced, thin, frequently oblique. Hydrothecal rim at right angle with the segment, with 9–11 cusps separated by deep embayments. Cusps rounded, sometimes uneven, with first abcauline pair clearly less pointed than others and almost blunt distally (

long, arising singly on hydrocladia, laterally from base of hydrotheca of first cormidium. They are formed by a first small internode devoid of nematothecae, followed by a jointed antler-shaped branched structure arching over the gonothecae. Branches normally three (occasionally up to four), each with a single row of nematothecae and some internal septa. Nematothecae with wide apertures and finely crenulated margins. Gonothecae 1–2 on each phylactocarp, attached by a small pedicel to points of ramification; obovate and curved distally, with lateral aperture tilted towards phylactocarp. Sex could not be ascertained.

. In material of the species described earlier, every phylactocarp divided dichotomously to form a structure of three branches (Broch 1918; Schuchert 2001). In some colonies examined here (NEREIDA0610 RD67), however, one of the branches may divide twice, resulting in a four-branch phylactocarp.

The margin of the median inferior nematotheca is highly varied, although its position in relation to the hydrotheca is decidedly regular. Sometimes it is almost even, as depicted by Broch (1918), but at times it is deeply indented in the middle, roughly leaving two symmetric lobes and giving the impression of a bifid theca. Transitions between the two extremes occur. In most aglaopheniid species from the study area, the mesial nematotheca tapers distally when seen frontally, with its end rather thinner than its base.

The position of the centrally placed nematotheca on the internodes of the main tube varies. Normally, it is close to the apophysis, but sometimes the internodes are longer and the nematotheca is distant from it and is close to the proximal node instead (NEREIDA0610 RD63). One colony from this station is particularly delicate, having a thin stem and only a few accessory tubules, the hydrocladia are quite distant, and there are only a few phylactocarps. In addition, a colony from the Flemish Cap (FC07 L165), the largest known to date (7.0 cm high), has the longest internodes and deepest hydrothecae (
